Is It Cost-Effective to Turn Off the Pilot Light on Natural Gas Heaters or Stoves?

While it may seem like a simple decision, turning off the pilot light on natural gas heaters or stoves is a topic that deserves careful consideration. From a strictly cost-effective standpoint, this can indeed save you money. However, safety should always be prioritized. Let's delve into the details.

Cost Savings From Turning Off the Pilot Light

The pilot light consumes a small but continuous amount of gas, contributing to your overall energy expenses. By extinguishing the pilot light when not in use, you can conserve those resources and reduce your utility bills. However, the cost savings may not be significant in most cases.

For Stoves: Most modern stoves come with automatic ignition systems. The pilot light is typically only required for igniting the main burners. Turning off the pilot light can potentially save a dollar a month, if not more, depending on the usage.

Modern Safety Mechanisms

Modern gas appliances are equipped with various safety mechanisms linked to the pilot light, such as thermocouples and flame sensors. These components ensure that the gas supply is automatically shut off if the pilot light goes out unexpectedly, preventing potential gas leaks and associated risks.

Manufacturer's Instructions and Professional Help

If you decide to turn off the pilot light, it is crucial to follow the manufacturer's instructions. Some setups may require a qualified professional to help determine the safest approach. They can assess the specific setup of your gas appliance and guide you through the process.

Example of Savings vs. Safety

Consider my experience with a new hot water tank installed in 2020. This model does not have a full-time pilot flame. Instead, it uses a thermocouple to ignite the pilot flame and the main flame when needed. My furnace, installed in 1993, still has a permanent lit pilot flame but is energy-efficient. The amount of money I would save by shutting off the gas valve in the summer months is insignificant—just a few dollars at most and typically less than 100 Canadian dollars for four months (June 1 to September 30).

However, there are times when weather conditions can make a difference. For instance, after a hail storm, my furnace may need to kick on to warm up. Additionally, if temperatures drop below 13 degrees Celsius for several rainy days, the furnace may also start up.

Conclusion

In summary, while turning off the pilot light on natural gas heaters or stoves can save you a small amount of money, it's essential to prioritize the safety of your home. Modern appliances often have built-in safety mechanisms that help prevent gas leaks and other hazards. Always consult the manufacturer's instructions and seek professional advice if needed.
